EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 233,681, dated October 26, 1880.

Application filed June 25, 1880.

T 0 all whom it may concern:

Be'it known that I, ALBERT LANDsBERe, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Eyeglasses, of which the followingisa specification.

My invention relates to improvements in that class of eyeglasses in which the bridge or nose-piece connection between the eyeglassframes is made of two parts, secured together by loops and capable of being slid one upon the other, so as to elongate or shorten the nosepiece; and my-iuvent-ion consists of a spring coiled around the lower half or part of the nose-piece, and so secured to the loops that it will at all times tend to separate the loops from each other, and thus press the frames of the eyeglass against the sides of the nose.

My invention further consists of a flexible clip secured to the nose-piece to shield the spring from the secretions of the skin, and which is also used to clamp the parts together when adjusted.

Figure 1 is an elevation of an eyeglass with my improved sliding nose-piece or spring-connection. Fig. 2 is an enlarged perspective view of such nose-piece or sliding spring-connection with the springs detached.

In theaccom panying drawings, A represents a pair of eyeglass-frames of the usual construction. To each one of these frames, at a, is secured the curved part I) of the connection. The straight part c of one of the parts which forms the nose-piece passes through a loop, 6, which is rigidly secured to the free end of the other part, d, While the latter passes through the loop i, which is similarly secured to the free end of the part c, the parts 0 (I thus being adapted to freely slide upon each other to enable the connection to be elongated at will.

Whenever the nose piece rests upon or (No model.)

against the bridge of the nose the point of contact will become fouled by the greasy excretions from the skin, and the spring hereinafter described, unless shielded from such con- 5 tact, would after a time become offensively dirty, owing to the great difficulty in properly cleaning it. Hence at the center of the bridgepiece, and to the upper part thereof and on each side, the flange-clips h are secured.

The coil-spring 7c is coiled around the lower part, c, of the nose-piece, and so secured to the loops that at all times it will exert a tendency to draw the loops at toward. each other.

The flange-clips h are made of ductile metal, so that they maybe compressed together, and thereby secure the parts 0 d in position when the desired length of nose-piece has been determined. The clips h, made of ductile metal, are secured in any suitable manner to the upper part, 02, of the nose-piece.

What I claim'as my invention is-- 1. In eyeglasses, and in combination with two parallel parts, secured as described, the clips h, substantially as and for the purposes set forth.

2. The combination, with a pair of eyeglasses, A, connected together by a nose-piece composed of the curved pieces I) b, terminating in straight parts 0 cl, adapted to slide on each other, and provided with loops &0 on their ends, of the spring k, secured to said loops, substantially as described.

3. The combination, with apair of eyeglasses, A, connected together by a nose-piece constructed substantially as described, of the spring 70 and clips h,substantially as specified.
